    摘要: Polyamides are built up from, as fundamental building blocks (a), lactams or aminocarboxylic acids or mixtures of these,as fundamental building blocks (b), from 1 to 50 .mu.mol of at least tribasic amines or carboxylic acids per gram of polyamide,as fundamental building blocks (c), dibasic carboxylic acids or amines andas fundamental building blocks (d), monobasic carboxylic acids or amines,where (c) and (d) are carboxylic acids if (b) are amines, and (c) and (d) are amines if (b) are carboxylic acids,the equivalents ratio of the functional groups of (b) to the functional groups of (c) and (d) together is from 60:40 to 40:60 andthe equivalents ratio of the functional groups of (c) to the functional groups of (d) is from 15:85 to 60:40.
